Description A set of five pieces that, when put together, make 2 molds that illustrate the moulding process to make a Coca-Cola bottle at the Chattanooga Glass Company. All parts of the molds are made of steel. In the bottle-making process, "a" and "b" are linked together and then locked into "c" so that the bottle mold is upside down to make the parison mold. Next, the raw materials that have been melted in the furnace are made into individual gobs and then placed in the mold of "a", "b", and "c" where the gob is made into a parison, which is a shorter, thicker version of the bottle. The Parison is then transferred to the blow mold composed of "d", "e", and "f" where compressed air is blown into the mold until the bottle takes the proper shape.

a,b). The mold used to make a parison with interlocking grooves. Both halves have "13, Chattanooga, 383, A.F.G.W.U." stamped along the bottom. This indicates that the mold was used and perhaps made at the Chattanooga Glass Company. A.F.G.W.U. Stands for the American Flint Glass Workers Union. The numbers most likely indicate the mold number, the product number, or the job number, yet we do not know which number goes with which meaning.
c). The base that was installed on the bottom of "a" and "b".
d-f). The mold used to shape the parison into the final mold of the glass. The mold and the bottle inside follows the 1957-1961 product model. "d" shows the mold of the Coca-Cola bottle and the label. It has the number 383 stamped on it as well as the number 8-87 and A.F.G.W.U. stamped on the top.There are several small holes on the inside of the mold that are connected to bigger holes on the outside, which serve the purpose of releasing gas and pressure from the mold while the glass is being blown. "e" slides between "d" and "f" on the bottom and creates the mold for the base, which says "Chattanooga Tenn" and has a copyright symbol. It also has the number 383 and the number 8-87 stamped on the outside. "f" is the other half of the mold with a completed Coca-Cola bottle glued inside. The mould contains various grooves and also have the number 8-87 stamped on the edge and 383 Chattanooga stamped on the outside. The numbers most likely indicate the mold number, the product number, or the job number, yet we do not know which number goes with which meaning.
